Here are some key features and specifications of the Cummins NTA855-M350:

1. Engine Type: The NTA855-M350 is a 4-stroke, turbocharged, and aftercooled diesel engine. It operates on the compression-ignition principle, where fuel is injected into the combustion chamber and ignited by the heat of compression.

2. Power Output: The “350” in the engine name refers to the engine’s power output in horsepower (HP). The NTA855-M350 is capable of delivering 350 horsepower, making it suitable for a range of marine vessels and applications.

3. Displacement: The engine has a displacement of 14 liters (855 cubic inches). Displacement refers to the total volume of all the cylinders in the engine and is an indicator of the engine’s size and potential power output.

4. Cooling System: The NTA855-M350 features a liquid cooling system to regulate engine temperature and ensure optimal performance. This system uses a combination of coolants, such as water and antifreeze, circulated through the engine’s cooling jackets and a heat exchanger.

5. Fuel System: The engine utilizes a high-pressure fuel injection system, which delivers precise amounts of fuel to each cylinder at the right timing. This system ensures efficient combustion and improved fuel economy.

6. Control System: The NTA855-M350 employs an advanced electronic control system to monitor and regulate various engine parameters, such as fuel injection timing, air-fuel ratio, and engine speed. This system helps optimize performance, fuel efficiency, and emissions.

7. Emissions Compliance: The engine is designed to meet the relevant marine emissions regulations, such as IMO Tier II or Tier III standards. These standards aim to reduce harmful pollutants emitted by marine engines, promoting environmental sustainability.

8. Reliability and Durability: Cummins engines are known for their reliability and durability, and the NTA855-M350 is no exception. It is built with robust materials and undergoes rigorous testing to ensure long-term performance in demanding marine environments.

9. Service and Support: Cummins has a global network of service centers and authorized dealers that provide maintenance, repair, and technical support for their engines. This ensures that customers can access reliable assistance and genuine Cummins parts whenever needed.

It’s important to note that specifications may vary based on specific configurations, options, and the intended marine application. For detailed and accurate information, it is recommended to consult the official Cummins documentation or contact a Cummins representative.
